What Are the Ways of Implementing Linked List in Data Structure?

A linked list is a linear data structure that consists of a sequence of elements, where each element contains a reference to the next element in the sequence. In this article, we will explore the different ways of implementing a linked list in data structure using HTML.

Singly Linked List

A singly linked list is the most basic type of linked list. Each element, also known as a node, contains two fields: one to store the data and another to store the reference to the next node in the sequence.

To implement a singly linked list, we can use HTML unordered lists (<ul>) and list items (<li>). Here’s an example:

<ul>
  <li>Node 1
    <ul>
      <li>Data: 10</li>
      <li>Next: Node 2</li>
    </ul>
  </li>
  
  <li>Node 2
    <ul>
      <li>Data: 20</li>
      <li>Next: Node 3</li>
    </ul>
  </li>

  ..

</ul>

In this example, each list item represents a node in the linked list. Inside each <li> tag, we use nested unordered lists to display the data and reference fields of each node.

Doubly Linked List

A doubly linked list is similar to a singly linked list, but each node contains two references: one to the previous node and another to the next node in the sequence.

To represent a doubly linked list using HTML, we can modify the previous example by adding an additional field for the previous reference. Here’s an example:

<ul>
<li>Node 1
<ul>
<li>Previous: null</li>
<li>Data: 10</li>
<li>Next: Node 2</li>
</ul>
</li>

In this modified example, each list item represents a node in the doubly linked list. Inside each <li> tag, we use nested unordered lists to display the data, previous reference, and next reference fields of each node.

Circular Linked List

A circular linked list is similar to a singly or doubly linked list, but the last node in the sequence points back to the first node instead of null.

To represent a circular linked list using HTML, we can modify either the singly or doubly linked list examples by changing the reference of the last node. Here's an example:

<ul>
.

<li>Node N
<ul>
.
<li>Next: Node 1</li>
</ul>
</li>

In this modified example, the last node's next reference points back to the first node, creating a circular structure.

Conclusion

In conclusion, there are several ways to implement a linked list in data structure using HTML. Whether it's a singly linked list, doubly linked list, or circular linked list, you can use HTML styling elements like <ul> and <li> to represent the nodes and their fields.

By leveraging these elements and incorporating proper formatting with bold text, underlined text, and appropriate subheaders (<h2>, <h3>, etc. ), you can create visually engaging tutorials that are informative and easy to follow.
